Abstract

Two new layered hybrid organic–inorganic compounds [Zn(pyim)]2V4O12 (1) (pyim = 2-(2-pyridyl)imidazole) and [Cu(bim)2]2V4O12(H2O)·CH3CH2OH (2) (bim = bis(1-imidazolyl)methane) based on polyoxovanadates (POVs) and organic ligands decorated transition metal units have been synthesized by hydrothermal and solvothermal methods respectively. Single crystal XRD, fluorescence spectrum, magnetic measurement, IR spectra, powder XRD and thermogravimetric (TG) measurements were performed to analyze the structures and properties of 1 and 2. The structural analysis reveals that compound 1 features a two-dimensional {[Zn(pyim)]2V4O12}n layered structure, constructed by sine wave-like {V4O12}n4n chains, Zn2+ ions and pyim ligands. In the layered structure of 2, {V4O12}4− circles are connected by Cu2+ ions to form {Cu(V4O12)}n2n chains, which are further linked by {Cu(bim)4}2+ subunits to generate a hybrid layer of 2. The magnetic susceptibility measurement indicates strong antiferromagnetic interactions between Cu2+ ions in 2.
